Wu Sansi nevertheless remained a trusted advisor, particularly because he was also the lover of Emperor Zhongzong's powerful wife Empress Wei.
On account of his relationship with Wu Sansi, Ji Chuna, who was then a commanding general of the imperial guards, was made acting minister of storage (太府卿, Taifu Qing).
The next day, Wu Sansi had the acting director of the imperial astronomical conservatory, Jiaye Zhizhong (迦葉志忠) submit a report stating that the night before, that the star Sheti (攝提) had entered the constellation Taiwei Palace (太微宮), symbolizing that a faithful official had entered the palace and met the emperor.
Suoge heard of this plan and acted first, successfully attacking several Tang outposts and then sending an envoy to Chang'an to demand that Zong be executed.
Subsequently, in 709, the censor Cui Wan (崔琬) submitted articles of impeachment against Zong and Ji for corruption that led to disaster on the borders.
At that time, Ji had reached Hua Prefecture (華州, roughly modern Weinan, Shaanxi), and was arrested and executed.
